Delaware

Delaware's primary statutory source is the Delaware Code Online, maintained in cooperation with the Delaware General Assembly. The official online Code currently states that the version includes Acts enacted through May 22, 2026. Because this research is dated September 2026, later 2026 session laws should also be checked before relying upon a provision that may have been amended after that date.

The Delaware Registrar of Regulations is the official repository for state administrative regulations. It publishes both the Delaware Register of Regulations, which records regulatory changes, and the Delaware Administrative Code, which compiles regulations currently in effect.

Laws of Delaware — Session Laws

A systematic search did not identify a general Delaware statute establishing one permit for every event meeting a specified “mass gathering” attendance threshold.

Instead, Delaware uses overlapping regulatory categories including:

• Places of Assembly;
• special-event assembly licences;
• tents and temporary event structures;
• amusement attractions;
• fireworks;
• temporary food establishments;
• alcohol events;
• state-highway events;
• State Park events;
• marine events; and
• municipal/county permits.

A particularly important statewide threshold is the Place of Assembly system administered by the State Fire Marshal. OSFM's current 2026 application states that annual life-safety inspections are conducted for Places of Assembly as defined by NFPA 101 involving 50 or more people, and that an annual licence must be obtained. The Fire Marshal calculates the occupancy limit based on the current floor plan and use.

OSFM also operates a separate application specifically for a Place of Assembly License — Special Event.

Delaware's fire-code framework is unusually important because it is genuinely statewide.

Under Title 16, Chapter 66, regulations adopted by the State Fire Prevention Commission have the force and effect of law throughout Delaware's counties, cities and political subdivisions. More stringent local requirements may govern if they are compatible with state regulations.

Effective January 1, 2026, Delaware adopted updated standards including:

• NFPA 1, Fire Code — 2024 edition;
• NFPA 101, Life Safety Code — 2024 edition;
• NFPA 70, National Electrical Code — 2023 edition;
• NFPA 10 — 2022;
• NFPA 13 — 2025;
• NFPA 14 — 2024;
• NFPA 25 — 2023;
• NFPA 30 — 2024;
• NFPA 54 — 2024;
• NFPA 58 — 2024;
• NFPA 72 — 2025;
• NFPA 96 — 2024; and
• other incorporated NFPA standards.

These requirements are particularly relevant to assembly occupancies, occupant loads, exits, aisle widths, emergency lighting, fire extinguishers, cooking, LPG, generators, temporary electrical systems, fire protection systems, crowd management, tents and event structures.

OSFM's January 2026 assembly guidance expressly states that:

• exits and exit paths must not be locked, blocked or obstructed;
• aisles must remain clear;
• fire-protection systems must remain active and properly inspected;
• posted occupant capacity must not be exceeded;
• combustible/flammable decorative materials require prior OSFM approval; and
• pyrotechnic devices and open flames, including “cold” fireworks/cold spark machines, are prohibited under the published assembly guidance.

Any proposed indoor pyrotechnic, flame or spark effect should therefore be discussed with OSFM well before an event rather than assuming that a theatrical product marketed as “cold” is exempt.

2026 Delaware State Fire Prevention Regulations Update

Final Regulation 701 — Administration and Enforcement

Delaware Code — Chapter 66: Fire Prevention

Delaware does not operate one comprehensive statewide general building code administered in exactly the same manner as its statewide fire regulations.

Title 16, Chapter 76 gives the county governments authority to adopt and enforce building, plumbing and related construction codes. Incorporated municipalities may also exercise building-code authority under their charters and local legislation. This makes structural/building permit jurisdiction highly site-specific. At the same time, the Delaware State Fire Marshal performs a separate statewide fire/life-safety plan-review function.

Temporary stages, grandstands, bleachers, platforms, towers and other structures may therefore require both:

• county or municipal building/structural approval; and
• State Fire Marshal approval for applicable fire/life-safety matters.

Delaware Code — Chapter 76: Building Construction Standards

OSFM Building Plan Submittals

OSFM Site Plan Submittals

The Delaware Office of the State Fire Marshal is central to event safety. Unlike states where most routine fire-code permitting is devolved to municipal fire marshals, Delaware's OSFM directly administers substantial statewide licensing, inspection and permit functions.

Relevant functions include:

• Places of Assembly;
• special-event assembly licences;
• tents;
• amusement attractions and rides;
• fireworks displays;
• explosives;
• fire/life-safety inspections;
• fire-protection systems;
• plan review;
• occupant capacities; and
• crowd-manager training.

The Delaware Emergency Management Agency (DEMA) is a division of the Department of Safety and Homeland Security.

DEMA coordinates statewide emergency preparedness, response, recovery and mitigation. Local and county emergency-management organisations remain the first level of response, with DEMA coordinating state assistance when needs exceed local capabilities.

On August 10, 2026, Delaware issued Executive Order 26 adopting the Delaware Emergency Operations Plan as the state's comprehensive emergency-management plan under Title 20. The system integrates emergency support functions, interagency coordination and state/local response.

Delaware's Office of Emergency Medical Services operates within the Division of Public Health.

The state regulates EMS and ambulance-service systems, while actual event-medical planning must also be coordinated with local EMS agencies and the emergency-response system.

No universal Delaware statewide formula was located requiring a fixed number of first-aiders, EMTs, paramedics or ambulances per number of spectators at all events.

Requirements can, however, be explicit for specific event categories. Delaware's combat-sports regulations and permit procedures, for example, impose specific on-site medical staffing and ambulance requirements.

Delaware Office of Emergency Medical Services

Emergency Medical Services and Preparedness Section

The Delaware Division of Public Health is the principal state public-health authority.

For events, particularly relevant areas include:

• temporary food establishments;
• potable water;
• handwashing;
• liquid-waste disposal;
• toilets for food workers;
• communicable-disease controls; and
• environmental health.

No general statewide event-sanitation provision was located establishing one universal toilet-to-attendee ratio for every Delaware public event. Site-specific permit conditions, local requirements and activity-specific codes must therefore also be checked.

DPH Inspection Services

Delaware has a specific temporary-food-establishment regime.

The Division of Public Health states that temporary-food applications should be submitted in advance. Current state guidance specifies 10 business days.

A Temporary Food Establishment associated with a sanctioned event may operate for up to 14 consecutive days. State guidance also places limits on repeated temporary-event permits and imposes operational requirements involving:

• approved food sources;
• hot holding at 135°F or above;
• cold holding at 41°F or below;
• handwashing facilities;
• washing/rinsing/sanitising facilities;
• potable water;
• wastewater disposal;
• refuse management;
• overhead protection; and
• convenient toilet facilities for food employees.

Alcoholic-beverage regulation is administered by the Office of the Alcoholic Beverage Control Commissioner (OABCC).

Event organisers need to distinguish several different permit categories rather than assuming Delaware has one universal “special event alcohol permit.”

Existing routes include Daily/Biennial Gathering licences for qualifying organisations and a Temporary Large Event licensing framework.

Temporary Large Event

Delaware alcohol law defines a temporary large event as an event involving more than 1,000 people where food or drink is sold, served or dispensed and an admission ticket or fee is required.

This definition is important but should not be presented as Delaware's general mass-gathering definition. It applies within Title 4's alcoholic-beverage framework.

New Special Event Venue Licence — 2026 Change

Delaware enacted new legislation in May 2026 creating a Special Event Venue alcohol licence. The legislation uses a different event concept, including qualifying outdoor festivals, carnivals and similar activity.

However, as of 6 September 2026, OABCC states that applications for this licence will begin in November 2026. It should therefore be identified as an incoming regime rather than represented as a currently available licence.

Private security in Delaware is regulated by the Delaware State Police Professional Licensing Section and the Board of Examiners of Private Investigators and Private Security Agencies.

Title 24, Chapter 13 expressly brings event-related security work into the regulatory framework. The statutory definition of private security activity includes aspects of crowd and vehicle-flow control undertaken for protection of property and supervision of event-security staff.

Security guards must be properly licensed. Unarmed guards generally must be at least 18. Armed guards face additional requirements, including age, firearms endorsement, training and uniform/identification requirements.

Private security personnel are not automatically law-enforcement officers and do not acquire general police powers by virtue of event deployment.

Delaware Code — Chapter 13: Private Investigators and Private Security Agencies

24 DE Administrative Code 1300

Delaware should not be treated as a state where crowd-manager requirements exist merely because NFPA contains them. Delaware has actually adopted NFPA 101 through its statewide fire regulations and OSFM actively provides Crowd Manager Training.

OSFM's published assembly-safety guidance specifies a minimum trained crowd manager/supervisor for an assembly occupancy and additional staffing as occupant numbers increase, historically using the one additional crowd manager per 250 occupants principle. The adopted code also allows specified exceptions/AHJ determinations.

Because Delaware moved to the 2024 NFPA 101 edition on January 1, 2026, event planners should confirm the exact current staffing calculation with OSFM for their venue and event rather than relying solely on an older guidance-sheet section number.

Operational crowd-manager responsibilities should include maintaining clear egress, monitoring occupancy, identifying hazards, assisting evacuation and coordinating with emergency responders.

OSFM Crowd Manager Training

Place of Assembly Licence and General Fire-Safety Requirements

Temporary event structures in Delaware can engage two regulatory layers.

The State Fire Marshal has jurisdiction over the fire/life-safety aspects of temporary event structures, assembly use and site access, while structural/building approval may rest with the county or municipality.

This is relevant to:

• stages and stage roofs;
• FOH structures;
• temporary platforms;
• grandstands and bleachers;
• temporary seating;
• lighting/video towers;
• scaffolding;
• hospitality structures;
• temporary enclosed structures; and
• tents/membrane structures.

No single statewide Delaware “temporary stage engineering permit” applicable to every structure was identified. Structural certification and permit requirements must therefore be established with the local building AHJ in addition to OSFM.

OSFM Plan Review and Inspections

Delaware Code — Chapter 76

Delaware operates an explicit State Fire Marshal Tent Permit system.

The current 2026 application requires:

• applicant/event details;
• tent location;
• maximum occupancy;
• installation and event dates;
• a location drawing/sketch;
• certificate of flame resistance; and
• the current permit fee.

The application expressly requires compliance with Delaware Fire Prevention Rules and Regulations, adopted codes and ordinances.

The inspection/application process also brings in issues such as:

• exits and exit signage;
• emergency lighting;
• fire extinguishers;
• LPG placement;
• electrical installations;
• flammable liquids/gases;
• fire lanes and emergency access;
• flame resistance; and
• occupant capacity.

The precise applicability of NFPA tent requirements, separation distances, exit numbers and cooking/heating arrangements should be established with OSFM for the actual tent configuration.

Delaware State Fire Marshal — Tent Permits

2026 Tent Permit Application

Professional fireworks displays are regulated under Title 16, Chapter 69 and administered by the State Fire Marshal.

A public-display permit is required. The statute requires advance application and information concerning the display location, date/time, fireworks storage and the person responsible for firing the display.

A professional display requires financial responsibility of at least $1 million liability coverage per event.

The State Fire Marshal licenses fireworks shooters and inspects/approves professional display sites.

The distinction between outdoor professional fireworks and indoor/proximate special effects is important. Current January 2026 OSFM assembly guidance states that pyrotechnic devices, open flames, “cold fireworks” and cold-spark machines are prohibited in assembly occupancies. An event wishing to use any theatrical flame or pyrotechnic effect should therefore seek explicit OSFM determination rather than relying on marketing descriptions such as “cold spark.”

1 DE Administrative Code 704 — Fireworks and Hazardous Operations

Delaware has a dedicated Amusement Ride Safety Inspection and Insurance Act, administered by the State Fire Marshal.

A ride may not operate unless:

• it has been inspected for safety at least annually by the insurer or its contracted inspector;
• the required inspection certificate has been obtained;
• liability insurance of at least $1 million per occurrence is in force; and
• required documents have been filed with the Fire Marshal.

State Fire Prevention Regulation 704 additionally requires an amusement operator to apply for a permit at least 7 days before the first date of operation. Each time an amusement ride is set up, an electrical inspection is required from a recognised electrical inspection agency. No site permit is issued until OSFM completes a satisfactory site inspection.

Not every inflatable or recreational attraction automatically fits the statutory definition of an “amusement ride.” The statute specifically excludes some nonmechanised playground equipment. Event organisers should determine with OSFM whether a particular inflatable, bungee device, mechanical attraction or interactive installation is within the regulated category.

Delaware does not operate an OSHA-approved State Plan.

Federal OSHA therefore regulates most private-sector event-industry employers and workers in Delaware. This is relevant to:

• staging and rigging;
• temporary electrical work;
• falls/work at height;
• forklifts and material handling;
• heat exposure;
• emergency-action plans;
• workplace violence;
• temporary structures; and
• other workplace hazards.

An important jurisdictional distinction is that federal OSHA generally does not cover state and local government employees, and Delaware does not have an OSHA-approved public-sector-only State Plan.

OSHA State Plans — Delaware Status

Delaware has a detailed statewide Special Events Policies and Procedures — Traffic Management regulation.

It expressly covers events such as:

• sporting events;
• concerts;
• festivals;
• conventions;
• parades;
• fireworks displays;
• bicycle races;
• motorcycle rallies;
• marathons;
• seasonal festivals; and
• block parties.

A planned special event may have a direct traffic impact, such as a lane or road closure, or an indirect impact through unusually large crowd traffic.

DelDOT requires an organiser of a planned special event affecting the transportation system to obtain approval. Direct-impact events require a Special Event Permit and a temporary traffic-control plan. Temporary traffic control must comply with the Delaware MUTCD.

Within an incorporated municipality, the local government is responsible for approving an event on a state-maintained roadway after consultation with DelDOT; DelDOT still reviews the temporary traffic-control arrangements affecting the state route.

2 DE Administrative Code 2403 — Special Events Policies and Procedures, Traffic Management

Delaware Business First Steps — Special Event Permit, Roads

Parades, road races, bicycle races, marathons, marches and street festivals are principally controlled through the DelDOT Special Events framework where the transportation system is affected.

For municipal streets, organisers must also establish local permit, police and road-closure requirements. An event involving both municipal and state-maintained roads may therefore require coordinated local and DelDOT approvals.

DelDOT Special Events Traffic Regulation

Agricultural events can engage several Delaware regulatory systems simultaneously, including:

• OSFM assembly/tent requirements;
• amusement ride permits;
• temporary food controls;
• animal health;
• liquor licensing;
• local building/zoning controls; and
• animal-exhibition requirements.

The Delaware Department of Agriculture regulates animal health and interstate movement of animals.

An additional state-specific issue concerns exotic animal exhibitions. Delaware regulations contain an exhibitor-permit framework and provisions concerning advance notification, public-safety planning and animal-health information.

Delaware Department of Agriculture — Animal Health Regulations

Delaware Exotic Animal Regulations

Ordinary stadiums, arenas and sports venues are primarily governed by the statewide assembly/fire framework plus locally adopted building codes and any activity-specific licensing.

Delaware has particularly detailed state regulation for combat-sports events.

For example, professional MMA events require a state event permit and prescribed medical and safety provision including:

• on-site EMTs;
• an ambulance;
• paramedic support;
• Delaware-licensed physician coverage;
• security;
• participant/event insurance; and
• required bonding.

The application process specifies advance filing.

Delaware Division of Professional Regulation — Combative Sports

Professional Mixed Martial Arts Events

Amateur Mixed Martial Arts Events

Combative Sports Entertainment

No separate Delaware state “concert venue licence” was located that replaces the normal assembly, fire, building and liquor systems.

A theatre, arena, nightclub, concert hall, convention centre or other major entertainment venue should be examined through:

• OSFM Place of Assembly licensing;
• occupant-load controls;
• means of egress;
• crowd-manager provisions;
• fire protection;
• local building approvals;
• alcohol licensing;
• private-security regulation;
• special-event permits where use changes; and
• traffic-management requirements.

Delaware's alcohol statutes also create specialised liquor categories for facilities such as concert halls and multi-purpose sports facilities, but these definitions are alcohol licensing classifications, not substitutes for fire/building approval.

Place of Assembly Licenses

Delaware accessibility requirements require careful jurisdictional distinction.

The Delaware Architectural Accessibility Act applies particularly to facilities constructed, leased or financed by the State and includes recreational areas and related accessible facilities.

Delaware's Architectural Accessibility Board itself explains that Delaware does not operate one uniform state accessibility building code for every building. State accessibility standards interact with applicable local building codes and federal ADA obligations.

Delaware also has state equal-accommodations legislation prohibiting disability discrimination in places of public accommodation.

Delaware Architectural Accessibility Act — Title 29, Chapter 73

Architectural Accessibility Board — FAQ

Delaware Equal Accommodations Law — Title 6, Chapter 45

19 DE Administrative Code 4101 — Architectural Accessibility Standards

Delaware's geography makes certain hazards especially significant for outdoor events.

The Delaware State Hazard Mitigation Plan identifies major hazards including:

• coastal flooding;
• tropical cyclones;
• inland flooding;
• severe winter weather;
• coastal erosion;
• severe thunderstorms and tornadoes; and
• extreme temperatures.

For event planning, the principal operational hazards include:

• hurricanes and tropical storms;
• storm surge;
• coastal/inland flooding;
• lightning;
• damaging winds;
• tornadoes;
• excessive heat;
• winter storms, snow and ice; and
• coastal evacuation constraints.

There is no general state event rule located requiring cancellation at one universal wind, lightning or heat threshold. The event emergency plan should therefore contain venue-specific trigger points, monitoring responsibilities, shelter/evacuation criteria and coordination with emergency-management authorities.

Delaware State Hazard Mitigation Plan

DEMA — Natural Disasters

Delaware Extreme Heat Information

The Department of Natural Resources and Environmental Control (DNREC) is Delaware's principal environmental regulator.

Potential event-relevant issues include:

• noise;
• generators;
• fuel;
• air emissions;
• waste and recycling;
• wastewater;
• activities affecting waterways/wetlands; and
• use of DNREC-managed property.

Delaware has a state noise regulation. Local noise ordinances or permit conditions may also apply, so the state regulation should not be treated as the only possible noise control at an event.

The most directly event-relevant Delaware child-law provisions concern employment and entertainment performers.

Title 19, Chapter 5 regulates child employment. Children under 14 are generally prohibited from employment subject to statutory exceptions, while workers under 16 and under 18 are subject to hours and hazardous-occupation restrictions.

A particularly important event-specific provision is §508: a child under 16 generally cannot work for compensation as a model, performer or entertainer in a stage, theatre, concert hall, theatrical exhibition or show unless the required Department of Labor special permit has been obtained.

Delaware Code — Chapter 5: Child Labor

The Delaware Department of Safety and Homeland Security (DSHS) includes the Delaware State Police and other public-safety functions.

For events, police jurisdiction depends on location. Municipal police, Delaware State Police or combinations of agencies may be involved in:

• public order;
• traffic;
• emergency response;
• crowd control;
• incident command;
• dignitary/VIP issues;
• suspicious activity; and
• major-event security.

Private security provision does not replace police authority where law-enforcement functions are required.

Delaware Department of Safety and Homeland Security

Delaware State Police

Delaware's state protective-security infrastructure includes the Delaware Information and Analysis Center (DIAC), the state-designated fusion centre.

The Delaware State Police Homeland Security Unit incorporates the DIAC and connections to the Joint Terrorism Task Force and other specialist resources.

Delaware also operates a statewide suspicious-activity reporting programme.

Delaware does not issue one universal state event permit. The principal state permits should be mapped according to activity and site.

Important examples include:

OSFM Places of Assembly and Special Permits

Delaware Road Special Event Permit

DNREC Boating and Fishing Event Application

Delaware State Parks are governed by DNREC regulations.

A person, group or organisation may not hold an activity or event requiring special arrangements, considerations or planning by State Park staff unless a written request is submitted to the Director for approval at least 7 days before the event.

Special arrangements can include issues such as:

• traffic/crowd control;
• additional parking;
• special equipment;
• unusual use of facilities;
• concessions;
• group activities; and
• other departures from normal park use.

The State Park permission is a land-use approval and does not replace OSFM, food, alcohol or other licences.

7 DE Administrative Code 9201 — Regulations Governing State Parks

Delaware has a specific state permit system for organised boating and fishing events.

Qualifying activities include:

• regattas;
• boat races;
• marine parades;
• tournaments;
• exhibitions; and
• other organised water activities.

DNREC states that a boating/fishing event application should generally be submitted at least 30 days before the event. Permission for the event does not automatically grant use of a boat-launch facility or other land, so separate site permission can also be necessary.

DNREC — Boating and Fishing Event Application

Delaware Code — Title 23, §2120 and Related Navigation Provisions

Delaware has a particularly relevant state-specific unmanned-aircraft law.

Under Title 11, §1334, subject to statutory exceptions, a person may not knowingly operate a drone over:

• a sporting event;
• concert;
• automobile race;
• festival; or
• another event attended by more than 1,500 people.

The statute also addresses flights over critical infrastructure and active first-responder incidents and contains privacy-related controls.

This is precisely the kind of state-specific event requirement that should be distinguished from general federal FAA rules.

The statute contains exemptions, so the 1,500-person rule should not be described as an absolute prohibition applicable regardless of operator status or authorisation.

Delaware State Park regulations separately restrict aircraft/drone activity on park land except in authorised/designated circumstances.

Delaware Code — §1334, Unmanned Aircraft Systems

State Park Regulations — Drone Provisions

Delaware event incident reporting is primarily sector-specific rather than based on one universal event-reporting statute.

Relevant systems include:

Amusement rides

The State Fire Marshal has direct enforcement authority over amusement-ride safety. Rides require annual insurer inspection and OSFM site approval, and the Fire Marshal can summarily abate operation where continued operation presents a life-safety threat.

No separate universal statutory “report every event injury to OSFM within X hours” rule was identified in the Chapter 64 material reviewed. Organisers should therefore check permit and operator conditions for any incident-specific requirements rather than inventing a reporting deadline.

Amusement Ride Safety Inspection and Insurance Act

Workplace incidents

For private-sector employers, federal OSHA's applicable serious-injury/fatality reporting framework applies because Delaware has no OSHA State Plan.

OSHA State Plans

Fire/explosion incidents

The State Fire Marshal performs fire and explosion investigation functions and has specialist licensing/enforcement responsibilities.

Professional MMA Events

Legislative Hall / Grounds Events

Qualifying external events on Legislative Hall property are subject to facility-use conditions including liability-insurance requirements.

Legislative Hall Facility Use Policy

The Delaware regulatory layer should be understood differently from Connecticut.

Delaware has three counties:

• New Castle County;
• Kent County; and
• Sussex County.

It also has incorporated municipalities with their own charters and local authority.

Areas commonly requiring county or municipal investigation include:

• building permits;
• structural permits;
• zoning/site use;
• local special-event permits;
• local road closures;
• local police requirements;
• local park/property use;
• local business/vendor licences;
• local noise controls;
• parking;
• traffic management;
• sanitation/site services; and
• temporary structures.

Fire/life-safety approval is more strongly centralised at the Delaware Office of the State Fire Marshal than in many states. A local building permit therefore does not replace OSFM approval.

Conversely, an OSFM assembly, tent or fire permit does not constitute county/municipal building, zoning or special-event approval.

Delaware Municipalities Directory

Delaware Municipal Charters

Delaware Business First Steps — Local Requirements

Authority Having Jurisdiction — Delaware

The Authority Having Jurisdiction (AHJ) principle is especially important in Delaware because different aspects of one event can fall to different authorities.

For a substantial event, the relevant AHJs may include:

• Delaware Office of the State Fire Marshal;
• county or municipal building official;
• county/municipal zoning authority;
• Delaware State Police or municipal police;
• DelDOT;
• Division of Public Health;
• OABCC;
• Delaware Emergency Management Agency;
• local emergency-management organisation;
• local fire/EMS service;
• DNREC;
• Division of Professional Regulation; and
• the government agency controlling state-owned land.

The Delaware State Fire Marshal is particularly important because its regulations operate statewide. Organisers should not assume that “local fire marshal” arrangements used in other states describe Delaware's system accurately.

Delaware's statewide fire system is sufficiently distinctive to warrant separate emphasis.

OSFM directly provides event-specific routes for:

• Place of Assembly licences;
• Place of Assembly special-event licences;
• tents;
• amusement attractions;
• amusement rides;
• fireworks;
• explosives;
• haunted houses;
• crowd-manager training; and
• assembly inspections.

Places of Assembly and Special Permits

Delaware separately identifies Haunted House Permits within its State Fire Marshal special-event system.

This is relevant to seasonal Halloween attractions, temporary haunted houses and similar entertainment uses where altered layouts, darkness, combustible scenery and unusual egress conditions can create significant crowd-safety hazards.

Delaware Haunted House Permit

Events on Delaware state-government grounds may require specific facility permission.

The Legislative Hall Facility Use Policy governs use of Legislative Hall and associated grounds. Applications are generally required in advance and conditions can include insurance, security and facility restrictions.

The State's Division of Facilities Management separately manages reservation requests for the Legislative Mall.

Legislative Hall Facility Use Policy

Legislative Mall Reservation Request

Delaware's unmanned-aircraft provision is unusually relevant to public-event safety because the statute itself identifies major event categories.

Subject to statutory exceptions, the law covers drone operations over:

• sporting events;
• concerts;
• automobile races;
• festivals; and
• other events attended by more than 1,500 people.

This requirement should be included in any Delaware major-event aviation/drone planning checklist.

Delaware Code — Unmanned Aircraft Systems

For a significant Delaware event, the organiser should establish at an early stage:

• Exact site and property jurisdiction — private, municipal, county, State Park, Legislative Mall or other state property.
• Whether the event/site is a Place of Assembly under OSFM rules.
• Whether an OSFM special-event assembly licence is required.
• Approved occupant load.
• Required crowd-manager provision.
• Means of egress, aisle and exit arrangements.
• State Fire Marshal approval for tents.
• County/municipal structural approval for stages, towers, seating and temporary structures.
• Fire lanes and emergency-service access.
• Temporary electrical installations and recognised electrical inspection.
• Cooking, LPG, generators and fuel arrangements.
• Fire extinguishers and fire-protection systems.
• Whether any proposed “cold spark,” flame or pyrotechnic effect is acceptable to OSFM.
• Professional fireworks permit and licensed shooter where applicable.
• Amusement attraction site permit.
• Annual ride inspection and $1 million ride liability cover where applicable.
• Temporary-food permit and 10-business-day submission period.
• Correct OABCC alcohol licence.
• Whether the event meets the alcohol-law definition of a temporary large event.
• Licensed private-security company and licensed guards.
• Police/security/public-order plan.
• EMS and ambulance provision based on risk and any activity-specific rule.
• DelDOT permit and traffic-control plan.
• County/municipal road-closure approval.
• Parking and pedestrian-management arrangements.
• State Park special-event permission if applicable.
• DNREC marine-event permission for water activity.
• Environmental/noise requirements.
• Emergency plan integrated with DEMA/local emergency-management structures.
• Severe-weather monitoring for hurricanes, flooding, lightning, wind and extreme heat.
• Accessibility requirements.
• Child-labour/performer permits.
• Drone controls, particularly for events exceeding 1,500 attendees.
• Insurance/bonding requirements.
• County/municipal building, zoning, property-use and special-event permits.
